Snow has fallen in the Sahara, covering desert dunes in a layer up to 40cm deep.

Snow started falling on the Algerian town of Ain Sefra in the early hours of Sunday morning(Jan.11), giving children an opportunity to race each other down the slopes. Rising temperatures meant it began to melt later in the day.

It is the third time in nearly 40 years the town, known as “The Gateway to the Desert”, has seen snowfall.
